Ground Vibration Detector

The Ground Vibration Detector is one of KETAK's early special-application projects in field surveillance. The device was designed to detect changes and vibrations on the ground surface, providing immediate visual and audible feedback to the operator.

Built in 1965 for surveillance needs, it could support scenarios where discreet recognition of underground activity or natural ground movement was important. The development emphasized simple operation, reliability, and performance under realistic field conditions.
